If you look at the details of the exception that is thrown you will see what SMTP command generated the error. that might tell you more about what went wrong.

Do you have a SMTP service installed and running as a Windows Service on the same machine defined as "localhost" ?

[Plater]

Are you catching the exception as the base Exception or as an SmtpException?
The SmtpException will give you extended information about the failure.

[mahmodm3]

no i haven't SMTP runing

sooo i need help give me a solution

[Plater]

Well if you don't have an smtp server running, how do you expect to connect to it?

then how can i run this thing ??

[Plater]

I can think of two ways:
Open up a command prompt (cmd)
and run:
net start "Simple Mail Transfer Protocol (SMTP)"

Or run services.msc and look for the SMTP service and start it.

some more information would help as we can guess from the code but this may not always be correct as you may have just found the code and be trying to use it incorrectly

are you trying to send on a network that is using exchange servers?

are you trying to send from a specific smtp server?

if you are connecting to a smtp server where are you intending to get the logon details from as with exchange you can use your standard network credentials but I don't think you can with SMTP

I have sent some stuff via exchange so don't have a lot of experience with doing smtp but this information will help clarify things a bit

[mahmodm3]

so i don't understand what are you mean exactly
but if you have another code than can i send an email please
tell me what is it

I haven't got an exchange server at home to work out the code but try having a look at this thread -

http://bytes.com/groups/net-asp/665140-sending-email-vb-net-via-exchange-server-2007-a

if you have any problems I will try setting something up to work it out.

[jg007]

also you are pointing to your SMTP server as ' localhost ' which will redirect back to your PC, if you check the code you will see that it will usually point to a server running either exchange or an SMTP server, to confirm if it is runnning smtp you could try using telnet on port 25 unless it is set up for a different port

If you are making a WinForms app, you can do it using MAPI, and use MS Outlook (or other mail client) to send your mails.

Google for ".NET MAPI" (e.g. http://www.codeproject.com/KB/IP/SendFileToNET.aspx).

This way you don't have to worry about the SMTP server, but rather pass the mail to Outlook, which will then use its own stored account settings.
